1. It takes a lot more effort than gun hunting. I was hunting on game lands near state college last year and moved stands many times looking to pattern this one 10 point. I saw him twice and each time, i knew the general area where he was going to be but not the exact trail he would be using. Both times, I could have easily killed him with a rifle....60 yards...but with a bow, it just ate at me all season that i had walked over his trail not 2 hours before!
2. Anyone can just go out with a rifle and get shots at deer, at least from my prospective
3. You have to be close to your prey. (goes with my example from number 1). With my rifle two years ago, I had 7 doe run right up to me at like 15 yards while hunting on the ground. They stopped and i could have shot anyone of them. To get a shot off with a bow would have been hard but with a rifle, all i had to do was pull up and pull the trigger. They stayed there for about 2 minutes before bolting but it would have been too easy.
4. Bowhunting is more of a rush because typically you see the animal and have to wait for it to come into range. This really gets the heart pumping! With a rifle, you can see a deer in 2 seconds, be on it and pull the trigger. Take for example rifle season in PA two years ago, I have just driven out some pines for my dad to try and get him a deer. I only kicked out a few grouse so we sat under this big pine tree and had lunch for about 15-20 minutes. In a matter of 5 seconds, 2 doe ran out into the field, my dad was on the bigger one and dropped it just like that. Really anticlimatic in my opinion.
5. Getting to watch your arrow fly perfectly through the kill zone
